Donation problems

[bansheeboie]

Hey fellas, I was riding the cub on Sunday when a plug decided to back out and eat up my dome thread. I know it's detonation but not sure what it's from. I have 24cc domes and had 149 150 compression, on 93 octane. I think it kud have been from not enuff gas bc I had to use a smaller fuel line due to my normal size gas line melting to my pipe. It could also be from squish but I haven't checked and I don't kno how to. The plug that backed out did look a little leaner than the other, that was the side i had to put smaller fuel line on. I did a leak down test already and passed. I'm goin to order a new 24cc dome and a set of race gas domes from hjr. I already got new fuel Line on the way. All help and knowledge is appreciated. Thanks-rob

What is your timing set at?

[mike0chek]

my guess would be that smaller gas line leaning it out..

[bansheeboie]

Timing set at +4. I'm thinking the same thing mike o, that smaller gas line kid be the problem

Why would you run smaller gas line. If there is a problem, stop, shut it off, tow it back, fix the problem correctly, then go back to riding...

ya these motors dont like to be lacking fuel so get the right line back on it before rippin again.

if nothing else fixes it, try backing down the timing some. +4 SHOULD be ok but you never know.
