Hey again... I'm starting to feel like leach on this forum because I keep asking for way more advice than I'm capable of giving back. All I can really offer in return is my thanks, so thanks!
This is the story today:
I've remounted a motor to my Frankenstein bike, and I can't get it to start. I've been following the sticky post in the 2-Stroke engine forum, and here's what I've been through so far.
-Tested for spark with plug grounded to side of engine. I've got spark.
-Dropped float bowl to check for fuel. I've got fuel.
-Drained gas, killed some weeds with old gas, and got new gas.
-Attempted a tow start. My neighbors are most likely organizing a petition to evict me after seeing that escapade.
-Moved carb needle to leanest setting (I fear I may be flooding something at this point after all the failed start attempts).
-Replaced spark plug after reading that sometimes plugs fire under test conditions but won't fire under compression.
The engine sounds like it's got pretty good compression. I have a expansion chamber exhaust on it (not SPB style, but the big chrome banana looking kind), and when I open the throttle a bit, I get a really pingy high pitch popping noise. I think that's a good thing, like the pressure is resonating through the chamber, right?
The only thing I can notice which seems off is the clutch... Even with the clutch disengaged, I can roll the bike more easily than other MB's I've put together. The motor turns over, but it's not as hard to turn over as before. Should I look into clutch adjustments more, or is it okay as long as it still turns the motor over?
I'm tempted to throw this thing off a bridge into a river, but that'd even be worse for the environment than riding it, so please, guide me once again, MBc community!
