Hello
Hope someone can help.
Ran up engine today with muffs as usual but after a few minutes running I got the overheat alarm sounding.
Had plenty of water from the telltale. I allowed it to cool down and checked the thermostat incase it was stuck shut, but was operating correctly. I wasn't...
Hello
Right i think i finally found the underlying cause of my issue. The replacement float valves were not the same. The new valves I fitted that came with the kit altered the fuel bowl level by approx 2mm. I refitted the old float valves.
Idle is much better, but I'm stuck with a flat spot...
Hello
Could anyone tell me if the Volvo penta AQ151B has a ballast resistor and where it may be located. I believe it has it and I think I've got the wrong ignition coil fitted. I've got a 3 ohm coil fitted.
Thanks David
Hello
Only ran for a minute at higher degree's. It's electronic ignition inside distributor. I removed heat exchanger to confirm timing belt timing marks. I'm going to replace timing bekt and tensioner while I'm that far.

Hello everyone
Checked ignition timing with strobe and was set approximately 6°. I loosened distributor and adjusted to see if i could get it closer and engine sounded better after a move in the slot. But to my horror I had turned it the other way. I increased the degree to approximately 15 °...
Yes I removed all the jets and cleaned the fine mesh filter on the feed to accelerator pump housing. My next port of call is confirming the ignition timing is correct. Hopefully get Down to boat in the next couple of days.

Hello
Thanks for your reply. I wouldn't be Intrested in buying, but thanks anyway. Also I'm in Scotland, wouldn't want to cover the cost of postage.

Hello
Hopefully I've manage to borrow a vacuum gauge to identify if plates are in sync. I set idle mixture screws to 2 turns out from seat to start but the mixtures screws ended up way more than 1.5 turns out in the video above.
Thanks David
Hello
Engine was running fine before carburetor rebuild. I decided to rebuild the carburetors because they had never been touched in the 10 years I've owned the boat. Wish I never disturbed them now. I ran the engine the day I removed carburetors with no issues.
The only other recent work was...
Hello Scott
Thanks for your reply. I've had the carbs apart and checked with compressed all passage ways. I've backed off the nut on the accelerator pump and both squirt but still seeing the same issues.
One observation I did make was if I cover the small Hole on top of carburetor which is...
Hello
Has anyone experienced these issues before. Engine will idle nice, around 900 rpm. It will rev to 1500rpm but between 1500 and 2000 rpm it wants to die. Once above 2000 it will rev but won't hold the revs. I've took video. If someone has ever had these issues please get in touch.
Thanks...
Yes I'll make sure I get them checked out.
Regarding the setting up of the accelerator pump, at what point should they squirt? Just before throttle plates open or the exact same time?
Thanks David
Hello Scott
Thanks for your reply.
I Blew compressed air through all passage ways. Like you say I may have a blocked passage way. Would there be a way to identify which carb may have the blockage? While running.
Thanks David
Hello
After a carb rebuild I am experiencing some issues. I can get engine to start and idle good. Upon accelerating the engine will die around 1500 rpm. I can get it past this point by pumping the throttle but it will not hold the high rpm. It will eventually drop the high rpm and die.
I've...
