Using blue loctite as a gasket seems like a bad idea to me? Surely the heat would just melt it very quickly, letting it run in the engine?

No it doesnt melt and it doesnt run anywhere. Locttite is a cyanoacrylate compound and heat will degrade it not melt it, his doesnt happen though much below 200C, much hotter than our engines run. If you dont like the idea fine, dont try it! But it has worked well for me and I've been through the whole range of gaskets, silicones and dry lapping techniques!

The question about applying the PC Fahrenheit epoxy has been asked multiple times here in this thread, and several others on different sites, and either everyone seems to ignore it, or doesnt know. Does anybody "really" use this stuff???
I have been neglecting using it just "because" it seems pretty horrible to apply! I couldnt imagine what that stuff would do to your piston/sleeve if a piece of it broke off and went up through it. So how do you apply it? I know finless don't really visit these parts much any more, but how about a bit of an illustration on a half decent method to apply it? I honestly tried it on my 91 HZ with Funtech B301 pipe today, and talk about a miserable experience! If anyone knows this pipe at all, you would know it comes with a fairly large adapter plate. I have had nothing but issues getting this muffler to seal with aluminum gaskets, fiber gaskets, or even Red Silicone. I would very much like to see this epoxy work for me, since everyone seems to rave about how well it "does" work. I havent flown on this stuff yet. What I did was tighten the screws down just enough so that that epoxy started to squish out of the edges of the flange; then let it sit until it cured. I then removed the screws and applied Red loctite and snugged them back down evenly. If anybody here really has good experience with this stuff, please tell us what works for you. Thanks! |

After a closer look i concluded that the long M4 bolts are just a hair too long making it impossible to seat the pipe to the plate properly. Shave some off the bolts resolved it. And i just use normal rtv to seal, never had any problems with it.

I tried the PC Fahrenheit on both the adapter plate to muffler, and Adapter plate to engine, and the engine side leaked out real bad; the worst of anything yet, but I think it was because I took too long getting the surfaces mated. On the side of the muffler to adapter plate the stuff sealed it off great. I shouldnt have to remove the plate on that side, so I'll leave it, and I've went to Red Silicone on the engine side. I havent had the time to give it a go yet. |

I use the PC Fahrenheit putty on my ys 56 and outrage pipe. It is miserable to work with, but so is RTV IMHO. I put a thin layer on the pipe side and clear the exhaust port with a small screwdriver. I then bolt the pipe on and cinch it down tight and clean off the excess that squished out. I then leave it like that and fly. The material is making a gasket, if you back the pipe off again it defeats the purpose.

That stuff bonds reallly well; the problem is; its sets up way too fast. I dabbed my fingers in water, and pressed it out nice and flat on a sheet of heavy paper. The water seemed to slow the process down a bit. I applied it as quickly as I could then sinched it down real tight like your saying, but I thought after I confirmed that it still leaked, that it was maybe because I went too tight and squashed it all out. SO what method do you do to secure the screws? Do you use Red loctite and apply it right up front, or do you tighten after the engine gets to temp? |

Got a OS 50SX and when I give it throttle the engine will die if I don't ease it up. It's like it either drowns out or not getting enough fuel at first. It runs good after the rpms get up. Any body got any ideas?

Low needle too rich? Without seeing/hearing it, hard to say. Go back to factory settings and start fresh.

After engine start up and while it is operating on low idle (NOT idle up) rpm's the engine tends to collect a bit of extra fuel on crankcase. When You open the throttle pretty fast, the extra fuel from crankcase will go to combustion chamber and coold down the plug / st down the engine.
On take off I usually 'pump' the revs up carefully from idle untill I can hear that engine collects revs nicely and then don't need to think about it untill next take off.

Thanks for the responses.
@ cory I've tried leaning the low end may be I didn't take it far enough. @ pilot4fun yep, thats what I have to do too. Either pump it a little or bring up the throttle real slow. It only does it on my OS 50 SZ though. I have a OS 55 that it doesn't do it on.

Please don't continue w/o going back to factory settings. Too lean=buy new motor.

I tried tunning my os 55 hz-r. I never hard the engine go lean like on the video. so I moved the main needle to one turn out and I still did not get the motor to ping or brake up. so I went back out to 1 3/4 and the motor is making good power and running at around 200F right after some hard tic toc.

Regarding doubling the fuel tubing up at fittings to help prevent leaks... Is there a trick to doing this? Do you use a small peice or fold the line back over itself??
