I have gone through at least 4 gx390 pull starters on my built predator 420 in the last 5 months, with the rope and plastic breaking. I want to see if other people are having the same issue.
Rope and center round plastic mechanism that engages the starter cup.What part and where is it breaking ??
Pics?
Ill get u some pics tomorrow As for engine mods, it has a billet rod, billet flywheel, 50lbs valve springs, governer and balance shaft delete, and a 34mm carb.That does sound unusual...
Lets see some pics of the cup and starter mech....
I reckon something is awry with the fitment....
Edit:What mods do you have done with the engine?? new flywheel??? ...
Yeah now that you mention that, It might be higher compression coupled with a cheap starter. ThanksSounds like a higher compression is causing it to come apart.
Your spot on mckutzy! the last time I changed out the starter I noticed the cup had a slightly bent spot, and sometimes the cord is jerked out of my hands but I always thought this was an issue related to advanced timing. When I get some time Ill try and swap out starter cups as I have a couple of extras laying around. And yes its a factory cup and housing.Does it have factory starter cup and blower housing???
It almost sounds like the cup is out of standard alignment with the starter pawls...
They will bind and hang up if the housing isn't seated correctly, or if the flywheel is offset not being stock...
Or... It's got alot more go off the bat, that it can't disengaged as it's going... but then it would have ripped out the pull cord out of your hand...
Just spit balling... But those things off hand are what I can think of...
Interesting situation...
Nope, pretty smooth operationHmmm... interesting...
When you pull the cord for the first few inches.... does it have any resistance or hangups.... or just fine till it contacts the cup???....
