I working on 89 2.3 ,the timing belt slip away from the mark and boat hard to start. I replace new belt,the engine still hard to start and when it run like no idle I use timing light check the mark on pulley show away from the mark on cover like 32* I try turn distributor back to 10* the engine die wrong run.can anyone tell me what wrong

the engine might be interferance fit,that means when the timing belt broke the valves can come in contact with the pistons causing them to bend.im not familiar with your engine but a lot of engines are interferance fit.

This app is a 120 hp 4 banger ford marine app. it should have points and condenser. Make sure you have the correct points installed. If the spring / arm for them is too weak they will open up too far apart.

First you have to make sure all the timing marks are aligned and that engine has a shaft that turns the distributor so if you're off a tooth on that shaft the distributor..as for that engine being a interference engine out of the many that i have done and that have snapped none of them ever had valve issues with the piston hitting them.. the only 2.3 interferance model that ford had was the diesel one's back in the mid 80's..pull the cap and recheck your timing marks and make sure the dist is on #1..

you might need to google or youtube mustang 2 2.3 timing marks or timing belt replace.

Each cog on the belt = 7.5 ish degrees off 2 cogs 15* and so on. Fairly sure but its been decades since I souped them things up.

Just looked at the date I think he has it figured out by now/

thanks every one here help me many times. .....I got my 2.3 omc running now ,i think my point and condenser some thing wrong ,I go head swap pertronix kit for omc 2.3 ,after I install pertolnix kits engine start run good I took it to the lake run very good

Thanks for posting the updated fix. Back when I use to work on this engine many many years ago a lot times the no start or really bad idle and very poor throttle response seemed to be points & condenser related. many owners would have the wrong set up or improper gapped points and so on plus what I mentioned in post # 3. Anyways thanks for posting the fix, always like to know what happened after the fact.
