95 mercury xri 150

Hard to start when cold, i have to use the throttle to start it, smokes heavily at first, and once warmed up it idles and runs great. After sitting for longer than 30-45 min its hard to start again. Ive been running seafoam thru it. The Compression is good, and the plugs do not look bad but are 2 years old. Any help would be great, thanks

Replace the manual fuel pump diaphragm. Check the temp sensor wires for good connection at the top port cylinder head.

change plugs also

I Changed plugs this morning, starts great now on the muffs. Thanks

Im taking it out tmrw after church, hopefully it was just the plugs
