My 50 8n side mount is still non op. Original post is back on 6-14-13 if you're interested.
Original issue was really gummed carb...like 3/4" of crud built up/grew from a missing gasket. Water got inside and mixed with gas. Real mess.
Used to be old faithful tractor.
Carb is all cleaned out now, adjusted float to 1/4 + a hair using drill bit. All orifices wired and sprayed with carb cleaner...all channels clear.
12v batt on a 6 v system. I have a 12v coil. 6v coil got too hot.
Spark at all 4 plugs. Got reintroduced today to a nice bite when I thought I was insulated. yea.
Gap is .025 on lobes with flat gauge.
New napa coil, cap, rotor.
Replaced copper strip to condenser with 12 gauge wire.
Firing order 1-2-4-3. #1 is front most cylinder.
Figured out #1 on distributor cap aok by looking at flywheel for each setting. Ordered plug wires each way. One way, I get a backfire in intake (correct wiring) and the other a chug, chug out of carb (180 out).
I know Hobo said to get a spark tester, so I'll break down now and find one. Seemed to get a nice shock today, but I'll get one regardless.
So, with all this, when I crank it, I get an occasional sharp backfire from the intake outside #4.
I've read that intake backfire means running lean. This makes sense as my old carb was leaking air like a sieve...hopefuly, not so much now. I've been trying 1/5 turns on idler and 1.5 on the main jet. I get a better backfire when I let more gas in.
Gas is not that old. Couple months.
I wonder if my old paper fuel filter should be replaced because it's restricting fuel?
I really need to get this running, so we can sell it. Tough economy has killed my biz, am starting up new biz.
Appreciate any input....Dave
