new2the'shees Posted September 17, 2015 Report Share Posted September 17, 2015 66mm namura on stock jugs and head. Does not start cold without starting fluid...Rage cage helped rebuild carbs...jetting is correct for fmf sst and powercore 2's...Once started, starts 1st kick....

sheerider11 Posted September 17, 2015 Report Share Posted September 17, 2015 Compression? Quote Link to comment Share on other sites More sharing options...
new2the'shees Posted September 18, 2015 Author Report Share Posted September 18, 2015 /\ This.........or broke a ring Tons of comp. Would the ring prevent the motor from running properly when started? It runs great when it fires up...Just the first cold start needs starting fluid...

new2the'shees Posted September 18, 2015 Author Report Share Posted September 18, 2015 Anything to do with 32:1? or 93octane being too low??? Once started it runs fine and starts first kick... Quote Link to comment Share on other sites More sharing options...

new2the'shees Posted September 18, 2015 Author Report Share Posted September 18, 2015 Thanks guys...Which compression tester kit would you recommend? anyone have any quality ones for sale for cheaper than retail? Quote Link to comment Share on other sites More sharing options...
new2the'shees Posted September 18, 2015 Author Report Share Posted September 18, 2015 which sticky for leakdown tester would you guys recommend as well? Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted September 18, 2015 Report Share Posted September 18, 2015 Good testers aren't cheap. I'd recommend a name brand one. Harbor freight is not name brand. Doesn't need to be snap on but at least a craftsman or one from a napa. Any leak down will work as long as it seals. But if it runs fine like you say you may not have a leak. 1 Quote Link to comment Share on other sites More sharing options...

new2the'shees Posted September 19, 2015 Author Report Share Posted September 19, 2015 Hey guys, I rebuilt this thing. Bought it in pieces. P.O. said it had no compression to the point where he could push over easily with hand. Still ran though...Rebuilt top end to find it was 66mm. Bought Namura 66 mm bore piston kit. Started up fine. Carbs were overflowing. Cleaned carbs, Assembled and it wouldnt start easily. Intake leak in right boot...replaced...quad wouldnt start without starting fluid at first then started fine. Today, I poured a lil premix directly in cylinder and she fired right up. Left cylinder was backfiring and missing. Tried to run compression test but was probably doing it wrong, Anyhow, both looked in the same ballpark. Took carb off in last ditch effort. Turn bowl upside down, voila, a jet falls out of the bowl, 1.4 it says. I cannot find where she resides though...Could this jet be the core of my issues?
