Volvo AQ125A: WILL NOT START

[ronboi01]

I am new so go easy on me...LOL
I have a circa 1984 Volvo AQ125A in a 19.5 bayliner, I just bought, the day I looked at the boat it was running and puring like a kitten, then got it home, tried to start it and no luck. It did run out of gas I was told, here's were I'm at: has gas, gas is moving in carb, i can see it, has spark, tested coil, & points and put in new plugs and rotor cap and gas, it started a couple times for only 20-30 seconds, now it plain old will not fire at all??? Found the distributor lose, not lose enought to move by itself but enought to turn it by hand, I played with that moving it about 3-5 degrees in each direction, I could hear when it was def. not right but still no starting. I surely would appreciate any and all advise, If I missed pertinant info just let me know

Those engines don't have chokes, and are really cold natured untill the temp comes up.
Pump the throttle about 6 times while cranking and see if it will go.

Re: Volvo AQ125A: WILL NOT START

I've been going a round with a boat I recently bought that is very similar, 1983 19' bayliner, AQ125A. It had set up a very long time and was totally full of common problems. When starting on an old fixer upper I always check compression 1st thing, look at the oil, clean & re-set points, check that carbureator is clean and it has clean fuel. On these engines there are 3 gears for the timing belt. When the timing mark is set at zero the cam pulley should exactly match up timing marks on the valve cover and there is a little dot on the face of the intermediate shaft (which pulls the distributor). This dot should align with the notch in the backing plate behind that gear. The notch will be on the "passenger side" or port side. If the timing is set reasonably close, you have fire, compression, and gas then it should crank. I had several problems with corroded terminals which really has been a PITA chasing and cleaning...but it does purr like a kitten now...and I've still not got all of the engine back together but will have it in the water tomorrow. Good luck. Oh yeah, the condenser is on the side of the distributor...pull the wire off, and with the switch on you should have 12 volts to that wire...using a volt meter put the positive lead on that wire and negative lead to battery neg or to a good ground.
