Manlift odd engine problem

old · Feb 29, 2016

So one of my friend has this Manlift that has not been run in maybe 1.5-2 years. He asked me to get it running today so I went an looked at it. Has a Volvo overhead cam engine in it. When I first tried to spin it over it popped once or twice then nothing. Pull the air cleaner out and sprayed a bit of starter fluid in. I could see that it looked like smoke coming out of the air intake. Pulled the tube off the carb and held my hand on the air intake and instead of sucking on my hand it blew. I am thinking it has to be one of 2 problems. #1 stuck intake valves and or the timing has slipped as for the cam that is since it uses a timing belt. I can see the cam drive sprocket turning but that does not say it is in time.
Do you think I am on the right track??
Thanks

Stuck valve would be my first guess from sitting, but now you may have a bent valve as well

One I worked on with a Ford 4 banger had mud dobber nests in it an when he tried to start it, the nests went under the pulleys and snapped the belt.

My friend told me it was a Ford engine but if I remember right I saw where it said Volvo on it some place. But yes I could see that happening but in this case the cam is still turning so could be the valves stuck open it jumped time
