Status: offline 		Looks like two wood plugs are place in side the block to take up space. Reduce fuel builf up? The lower wood plug is larger than the upper one in the picture. Is there a science to this or how do you determine the correct size?

Status: offline 		The plugs are the same size. They just need to be fuel proofed or you can make some out of fuel resistant materials. The plane flew another three flights again today with no hickups. It just ran, and ran strong.

Thanks

Status: offline 		Patrickp has graciously offered his kit to me, and I would love to test one out and report back here.
The problem for me is that the kit is for the older wga carb. Patrickp has also offered to loan me a carb for testing but I would need to move around the throttle & choke servos and of course buy a old carb and the kit if it all works out.

Tony, Steve, I used plastic pulgs in my read block and it really didn't make much difference.

Status: offline 		Observation! When I look at post #880 by RTK and post #884 by Wings-RCU the blocks look like they are larger in Wings-RCU picture. If the block are there to reduce fuel pooling could a larger block reduce the pooling too much? Both of you are re-desiging the carb block to work in a different way. Could reducing the size a small amount on Wings-RCU block give him a better set up? Just a thought.

Status: offline 		So what happened to this thread? AKA as finding the fix for the 115 engine.

The testers have gotten lost in the clouds or in the triangle and do not have IFR to find a place to land.


Or they may have been captured by the enemy.


All owners are due the real fix and the right answers.


Let them know how the kit works and who should buy or supply the fix to the owners.


Mine works very well and yours can too.

Status: offline 		Hey Patrick: just to clarify, will your fix work on the original carb with the tall reed block as well as the others ? I'm waiting patiently to see what the testers think and if it works out (and I sure hope it does), how the ordering process is going to be handled. If it works it will save me from getting tuned pipes/headers as Kris recommends. The pipes are fine, but we don't have noise restrictions currently so I'd rather run compact mufflers to save a little weight if possible.

Status: offline 		As far as I can tell it won't matter what carb you are using I do have both kits for old vs new carb that came on the engines.

The engine ran poor/same with both carbs and the kit made the problem go away.

If you have the wga9a carb I do have a kit ready for that too.

It is not a carbkit.

It has nothing to do with the carbs at all.

Although having a tuned exhaust system will make more power overall.

The shorter the headers the more fussy things are to tune, for overall rpm ranges
short headers are for max rpm top end power.
The longer the header, they will make more low to mid range power. and are easier to tune.
With stock exhaust you have no header length. more pulses as explained by Kris.

So anyway you should be able to make run engine well, maybe not the very best but it should run.

Status: offline 		I spent two days flying with PatrickP - his engine ran great all weekend. It is like night and day.

What is going on with the guys that have the kits to try out? I got to tell you, I am sympathetic to Hammbones situation with his rudder. Having said that- watching him sit on the sidelines waiting for a rudder has convinced me that I don't want an FMG kit, even if they are beautiful.

Hammbone- why don't you just stuff your engine into your buddies plane and try it out? Winter is coming......
