340 no can start
the firing order is 18436572? I have a 340
If this is NOT a reverse rotation marine engine 18436572 is correct
Guy, there is NO reason you should not be able to set it up and start it just as if it was sitting overnight
1....Remove no1 plug, stick your finger in and bump on the starter. When you start to feel compresson on your finger, STOP, and look for the marks "coming up."
2....Wrench or bump the engine until the timing mark "comes on up" but do NOT set at TDC. Rather set where you want timing to be, 10BTC or so for a stock cam, and 15 even 20 for a "hot cam" Set the mark there
3...Drop the dist. in so the rotor is approaching the no1 coil tower as it turns CW. Set the dist so the reluctor is in the middle of the pickkup coil
4....You can check timing "on the starter." Hook up your timing light, crank it a few turns and you should be able to see the mark, chaulk or otherwise "whiten" it if necessary.
5...Since you've been messing with this, pull enough plugs to insure you don't have them all gas fouled (wet)
6...Make SURE you have fuel by pumping the carb, look for the accel. pump to squirt
7...Make sure you have some FRESH fuel. If there is any question at all, throw a tablespoon or so down the carb throat
8...You should now be able to crank it and AT LEAST get a "pop" or backfire or try to start and run
9....If this does not work, check your valve settings. Maybe something is wrong. Run a compression check on 3 or 4 cylinders at least
10....RE check RREEEEEE check your spark. Do this by "rigging" a gap at the top of the coil tower, and check BY CRANKING WITH THE KEY. This is because power is routed different in crank vs "run" at the key
