I have recentley bought a 1979 Tioga and after the first week of cleaning to make it respectable, have now started to come to terms with the nitty gritty part THE ENGINE. The journey back home from buying the van was fine but it started spluttering and back firing the first morning i started it from cold.So in the garage for a service she goes.Now im informed i need a new/recon carb.The guy is willing to take it out and soak then clean it first but if this fails then the fun starts. Is the engine compatable to any other make or is there an alternative,is this a common fault.I have a couple of others small snagsbut thought i would begin with the biggest! Engine manufacturer? Thanks in advance for any help or basic info on the engines for these things.
